Use cases

  • Hero image focal points

    Keep the most important part of a decorative background visible across varying container sizes.

  • Pattern alignment

    Place icons, textures, or repeated motifs consistently inside reusable components.

Cautions

  • Positioning alone cannot solve poor crop choices if the underlying asset does not suit the component ratio.
  • Responsive layouts may still need alternate assets rather than one heavily repositioned image.

Accessibility

  • If a decorative image supports the page mood, ensure it never interferes with reading or focus visibility.
